Try not to get confused with the amount of ski specialization, you don't need a different ski for every day you go skiing. Think about what you like to ski, think about what you actually spend the majority of your ski days skiing then honestly asses your ability level now and where you expect to get to while owning this new ski.
That should narrow down your choices and start to zero you in on a 'price range', Expert skis cost more than Intermediate skis which cost more than Novice skis... it's not a bad idea to buy a level above where you currently are, but letting your ego get in the way of reality and you'll over pay for a ski that won't be as fun as it could be.
Epicski is a great tool, there is plenty of opinions available here, there are many many skiers who have tried and/or owned almost any ski that you'll find. A little time spent reading about them will give you a decent idea of how others feel... that's good, but YOU are the only person that needs to love your new ski.
Demoing is the best way to figure out what you like, the problem is most 'Demo Centers' concentrate on the highest performance skis, you probably won't fing too many 'package skis' to demo, these are what most intermediate level value skis are refered to as. If you demo, try a few different brands, see what you like (and don't like) then try some different widths, see what you think. Keep a record of Brand/ Model/ Length and impression. Take this info and find the best ski for the best price for YOU.
